Alkaline primary batteries are generally not rated by capacity in mAh like you may find on rechargeables. This is because the actual delivered power in mAh is highly dependent on the discharge rate and cannot be standardized across all applications.

From another forum:
"Alkaline batteries have a significant internal resistance compared with rechargables. This means the greater the current draw, the more of their energy they waste generating heat in the battery.
Additionally, alkaline batteries supply a gradually decreasing voltage as they discharge, so for some applications they become useless even while they technically have a fair bit of energy left in them. Flashlights are a nice example - a mini-maglite goes from bright to sickly in about thirty minutes with alkalines, even though they'll give a weak beam for a few hours after that, and run a radio for a while even after that. Rechargables tend to have a relatively flat discharge curve.
This makes a mAh figure less useful for alkalines than for rechargables, or even downright misleading." see less

According to a part number cross reference, these are rebranded alkaline AA with a capacity of 2.875Ah.

I have looked at the batteries, the box they came in and on the website for this information. There is nothing available on mAh.

I bought this AA Batteries for "Cabinet Lights Ebeet 56led light "(Ebeet Motion sensor light)I have installed the EBEET light on the underside of the stairway, and it works perfectly. if you need, go to see it.

Every inexpensive battery is different even of the same type but on average alkalines seem to have more initial voltage and last half again as long as rechargeables but of course it doesn't cost anything to recharge the rechargeables as long as they remain rechargeable. I have a lot of rechargeables but have gone back to alkalines.

mAh ratings are only seen on rechargeables, and that will always be an "up to..." value that depends upon discharge rate. For any who are confused over AA vs AAA size on these reviews, Amazon has reviews for both products bucketed into one place (note the ability to swap from AA to AAA size with a drop-down selection on one single item page).

Tristen Hernandez is confused and incorrect, as usual, these are for AA batteries...
